1. What is m³/h to GPM Converter?

Definition: This calculator converts flow rate from cubic meters per hour (m³/h) to gallons per minute (GPM).

Purpose: It helps engineers, plumbers, and technicians working with fluid systems to convert between metric and imperial flow rate units.

2. How Does the Converter Work?

The converter uses the formula:

Where:

• \( Q_{gpm} \) — Flow rate in gallons per minute (GPM)
• \( Q_{m3h} \) — Flow rate in cubic meters per hour (m³/h)
• 4.402 — Conversion factor (1 m³/h = 4.402 GPM)

Explanation: The conversion factor accounts for the volume difference between cubic meters and gallons, and the time difference between hours and minutes.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for system design, pump selection, and ensuring compatibility between equipment using different measurement systems.

4. Using the Converter

Tips: Simply enter the flow rate in m³/h and the converter will automatically calculate the equivalent in GPM. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 4.402?
A: It combines the volume conversion (1 m³ = 264.172 gallons) and time conversion (1 hour = 60 minutes): 264.172/60 ≈ 4.402.

Q2: When would I need this conversion?
A: When working with international equipment specifications, comparing pump performance data, or designing systems with mixed units.

Q3: How accurate is this conversion?
A: The conversion is mathematically precise. Any inaccuracies would come from input measurement errors, not the conversion itself.

Q4: Can I convert GPM back to m³/h?
A: Yes, divide GPM by 4.402 to get m³/h (or use our GPM to m³/h converter tool).

Q5: Does this work for all liquids?
A: Yes, the conversion is based on volume flow rate, not affected by liquid density or viscosity.
